Totally normal, for all the reasons you stated. I also had 4 cesareans and my last was particularly hard recovery-wise. My dh was less helpful because I had recovered fairly easily before and had been in the hospital a week this time. So I didn't get as much help and the kids were more demanding of me thus less rest. The more you sit with your feet up the quicker you'll get back to normal. I remember how bad it hurts to carry that darn carseat when your scar feels like it's on fire. Each c/s is different, if you don't feel ready, you're not. Put your feet up and relax.
